IMPROVEMENT IN EARTH-AUGERS.

Specification forming part of Letters Patent No. 184,916, dated November28, 1876; application tiled April 25, 1876.

To all whom it may concern:

Be it vknown that we, GEORGE W. SHAP- LEY and DANIEL PHILLIPS, ofAustin, in the county of Mower and State of Minnesota, have invented anew and useful Improvement in Well-Auger, of which the following is aspecification:

Figure l is a top view of our improved Well-auger, part being brokenaway to show the construction. Fig. 2 is a side view of the same, partof the case being turned back. Figs. 3 and 4 are detail views of thelower reamers.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved well-auger, whichshall be so constructed as to enable a much larger hole to be y boredthan the diameter ofthe auger, andwhich shall be easily operated, andeffective in operation, moving the small stones from the center towardthe rim, so that they may be taken up by the cutters.

The invention will first be described in connection with drawing, andthen pointed out in the claims.

A represents the lower section of the shaft, to the lower part of whichis attached a Vertical squarc frame, B, the upper end of which isstrengthened by the braces O. To each of the side bars of the frame Bare hinged semicylindrical plates H, which plates H, when closedtogether, form the case of the auger, so that they may be opened toempty the auger. The hinges of the plates H are sliding or detachable,so that the said plates may be detached, if desired, for convenience inemptying the auger.

To the lower end ofthe shaft A is attached a screw-drill orreamer-shaped piece, D, to lead B, and project beyond the case H, so asto cut a hole of a larger diameter than the case H.

The reamers J may be made to project more or less to cut a larger orsmaller hole, by adjusting the block L upon the shaft A.

The earth loosened by the reamers J falls into the upper part of thecase H, and is received upon the partition K, attached to the shaf't Ato relieve the cutters E from its weight.

rIhe partition K may be made dat, or conical, or V-shaped, as shown inFig. 2. The latter construction is preferred, as it facilitates thedischarge ofthe earth when the case H is opened.

L are reamers, to be attached to the lower end of the auger when thehole has been sunk nearly to the requireddepth to ream out the lowerpart of the hole below the point where the reamers J can operate.

Having thus described our invention, We claim as new and desire tosecure by Letters Patentl. The combination of shaft A, frame B, andsemi-cylindrical plates H, the latter detachably hinged, substantiallyas and for the purpose described.

2. The combination, with shaft A, frame B, and Aplates H, ofthedrill-cutter D, mold-board cutters E, rim F, and points G, arrangedsubstantially as and for the purpose specified.

3. The reamers J, attached to blocks I, ad-

the auger into the ground, and push the earth justable on shaft A, asand for the purpose and stones outward from the center, so that they maybe taken up by the cutters E attached to the frame B, and to the rim Fattached to the bars or frame that supports the cutters E. The cutters Eare made of moldboard shape, which enables them to take up stones nearerto the center than they otherwise could.

To the cutters E and the rim F are attached points G, which 'project alittle beyond the said rim F, and are made something like described.

4. The combination of the partition K with the shaft A, and the middlepart of the case H, substantially as herein shown and described.
